Effluent Treatment Facility: Challenged to meet environmental restoration

摘要

The Effluent Treatment Facility (ETF) located in the center of the Hanford Site is designed to receive liquid effluents from several of onsite sources, process them to eliminate hazardous and radioactive materials, and then discharge in compliance with applicable laws in a suitable location. The design incorporates several technologies selected as the best demonstrated available technology (BDAT) for their particular purpose in the context of the wastes to be treated. These technologies include the following: Filtration; Ultraviolet (UV) oxidation of organic materials; Staged pH adjustment; CO(sub 2) removal (degasification); Reverse osmosis; Ion exchange; Forced circulation evaporation; Thin-film drying. In addition to these process technologies, the facility design includes semi-automated waste packaging systems, and an advanced integrated monitoring and process control system.
